I would assume that he means all Kalashnikov designs, -47, -74, and the 100 series.
I don't see it as very likely that the Russkies will buy a redesigned, rechambered AK from the Israelis. Why would they dump all their millions of AKs just to buy slightly different AKs in 5.56? Same goes for the French FAMAS (because who really does use them?) or the SA80. National pride and all...
I actually think they are more likely to spend billions of rubles developing and testing a completely new rifle and completely new round, then make unsubstantiated claims that it will shoot 10k yards, have no noticeable drop, and will penetrate tank armor, all while being self-cleaning.
Or, they can just blow their 2011 military budget and get a few hundred ACRs or SCARs
Side note, what the hell is the German G1 rifle...does the writer mean the G3 or what?
